Transformation and aftereffect of immobilized nitrogen (~(15)N) depending on the previous fertilization of soddy-podzolic soil

摘要

The thansformation of immobilized fertilizer nitrogen (~(15)N) applied after the long-term use of mineral fertilizers alone and in combination with manure in soddy-podzolic soil of the Western Siberian subtaiga zone was studied. The utilization ratesof remineralized soil nitrogen by field crops during the six years of aftereffect were determined.
